From BED file (genome regions) to GWAS

[gatapishi]

Hello and thank you for always help!!

Now I have got several significant regions of transcription factor binding and specific histon modification as bed files.

I want to know the relationships between these regions with GWAS results.

1. For example, as a input file I prepare bed file which include significant binding regions of NFkB.
2. Next I compare the bed file with GWAS total database which include significant region sets which might relate to some diseases.
3. Finally I want to got the most significant disease set that are related to start bed files.

I want to know such GWAS database or program for such purpose.
Do you know??
